Each range of the EMSNAME OF YOUR LESSONpage 2
C. Bailey, S. Brown, Y. Diaz, M. Farrell, C. Letcher, J. Swift, M. ZahreddinePrinted on 1/25/2017(Electromagnetic Spectrum) has several applications and uses in everyday life. All the radiation types aredistinguished by its own wavelength and frequency; radio wave having the longest wavelength and lowestfrequency while gamma rays have the shortest wavelength and highest frequency. The visible light is theonly radiation visible and when it pass through a prism it separate into different colors. The colors of therainbow are in a specific order based on their wavelength (red, orange, yellow, green, blue, indigo, andviolet).Lesson ProcedureEngageInclude guiding questions you might ask to help students. If you use a video (include the URL in your lesson plan instructions) ora book (the author, title and publication date), and include questions that you would ask before, during or after the video/bookreading selection.1. Instruct students to hold the end of the rope with their hand at their waist.2. Ask students to back up so that the drooping rope just touches the floor.3. Discuss the characteristics of the hanging rope.Question: What does the shape of the rope look like in a resting position?Question: How much energy do you need to use to keep the rope in this resting position?4. Ask students to slowly and gently move the hand holding the rope up and down (about one foot between topand bottom).5. Discuss the characteristics of the rope.Question: What is the shape of the rope now?Question: How has it changed?Question: How has the energy needed to move the rope changed?6. Ask the students to increase the distance between the top and bottom but to keep the same speed.7. Discuss changes in the characteristics of the ropeQuestion: What is the shape of the rope now?Question: How has it changed?Question: How has the energy needed to move the rope changed?8. Ask the students to increase the speed of the rope.9. Discuss the characteristics of the rope.Question: What is the shape of the rope now?Question: How has it changed?Question: How has the energy needed to move the rope changed?ExploreThis should be a student-centered, hands-on activity that teaches your students about science. No lectures or direct teachingallowed. Please be as hands-on as possible. Also, please provide enough detail so that Dr. Blanchard could teach your lessonbased on what you have included in these steps.1.2.3.4.5.6.Each group of students will receive 1 envelope. Inside the envelope are the different types ofElectromagnetic waves and pictures that correspond to each energy type. Blackline Master #1.See sheet below for answers.Allow students to match the pictures to the definition of the type of Electromagnetic wave theybelong to (based on prior knowledge). Instruct students to keep the cards on their desk once theyhave them matched.Once students have all pictures and Electromagnetic wave types matched, have them raise theirhands for you to come to check their work. Instruct students to keep the cards together once theyhave the order correct.If there are wrong matches, silently un-match those words and have students correct them untilall pairs are correctly matched.Have students write a working definition and draw a picture(s) in the space provided on BlacklineMaster #2.

You should have at least 10-15 questions toguide student discussion and learning.Some questions you might ask students include,1. Where does the radiation of the electromagnetic spectrum originate from?2. Are all wavelengths and frequencies the same? Explain your reasoning.3. Are there different types of waves in the spectrum? Are they in a specific order? How is thatorder determined? What would that order be?4. Which electromagnetic wave has the longest wavelength?5. Which electromagnetic wave has the shortest wavelength?6. What wave property increased as the wavelength decreased?7.What happens to the energy as the wavelength decreases?8. What is the order the colors in the visible light spectrum? Where would the infrared andultraviolet fit in the electromagnetic spectrum?ExpandInclude a similar student centered activity that will allow students to practice or connect what they have just learned in Explore.This is not an opportunity to introduce a new topic, but to provide enrichment on the topic of this lesson.1. Take a piece of paper and fold it in half (hot dog). Lay a ruler down along the top of the foldedside and fold it back up over the ruler, make six even cuts to make seven even flaps.
